This article delves into the differences between SC and LC fiber optic connectors, providing you with a guide to choose the connector that best fits your needs.
Fiber Optic Connectors: The Bridge of Connection
Fiber optic connectors serve as the bridge between fiber optic cables and networking devices, ensuring smooth and stable connections. Although various types of fiber connectors exist in the market, SC and LC connectors are the most commonly used types.
SC Fiber Optic Connector: The Classic Choice
The Standard Connector (SC) was introduced between the late 1980s and early 1990s and is one of the earliest types of fiber connectors on the market. It features a push-pull locking mechanism that ensures stable connections. SC connectors are most commonly found in video and audio cables due to their ease of connection and disconnection. Initially designed for Gigabit Ethernet, the SC connector’s ease of use, low cost, and outstanding performance have kept it a popular choice for point-to-point and passive networking over the decades.
LC Fiber Optic Connector: The Modern Choice
The Lucent Connector (LC) was developed in the early 2000s as an improved alternative to the SC connector. Despite the SC being a go-to choice for fiber optic connectors, complaints about its bulkiness and the ease with which it could be dislodged led to the development of the LC. The LC also uses a push-pull locking mechanism but includes a latch for added security. Although this modern connector initially struggled in the market due to high licensing fees, it eventually gained popularity and became indispensable in newer fiber applications like FTTH and in data and telecom centers.
Differences Between SC and LC Connectors
Here are the key differences that set SC and LC fiber optic connectors apart:
- Different Ferrule Sizes: The SC connector has a 2.5mm ferrule, while the LC connector has a 1.25mm ferrule. The smaller size of the LC connector makes it a better choice for offices and data centers.
- Design Differences: SC connectors use a straightforward push-pull locking mechanism, while LC connectors feature a latch system. Although the LC has a more innovative design, the SC is easier to use.
- Durability: SC connectors have been in use for decades, and LC connectors are relatively new. However, both have nearly identical insertion and return loss characteristics. They are both highly durable and offer excellent transmission speeds.
- Cost Differences: Due to their detailed design, which increases manufacturing costs, LC connectors are more expensive than SC connectors.
Choosing Between SC and LC Connectors
The choice between SC and LC connectors depends on the specific purpose you need them for. For instance, if you require fiber optic connectors for network connections in a data center, the LC is the go-to option because it allows for the connection of a large number of connectors. On the other hand, if you need a fiber optic connector at home to connect a fiber optic cable with a router, PC, or gaming console, then the SC connector should be selected. It is more affordable and durable.
